Try to resize the picture to exactly: 480x272. Thats the native resolution of the screen. I get ok results with that.

ok results for an oled-display is not enough for me ...why not exact the same quality lieke the original? Ive tried it with 272x480 but the device makes a copy an stores it in folder skins... if i compare the both pictures, its a big difference... in quality.

Make your own UCI... the picture you import in sdk for backgrounds is much better than your selected wallpaper... dont know why samsung is not using a pic directly for background... only poor copy-picture shit...

anyways... i got what i want...

Check this out... this is:

Use the pic for background.... look how bad is the result... after that, try the example-uci and you will see how much better it looks.

I tried and you're right: the m1 trys to downsize the image by reducing its quality (= higher jpeg compression). But I think I found a workaround:

Copy your wallpaper (size: 480x272 and moderate quality) to your pictures folder (or anywhere else). Disconnect the device and set this picture as wallpaper/background/my skin. Connect the device. Check the picture folder and browse to the subfolder "skin". Ther you'll find a copy of the wallpaper you just set. Just replace this copy with the original-good-quality one. Disconnect the device and start it: viola!

Problem is, after changing the background you have to do this procedure again.

Thats good but you can also create your wallpaper... save it as a "png"-file... after that just change the extension to"jpg" ... Overall-quality is much better!!!! If you have a good source for a wallpaper... the png-fileformat will do the rest... no need to use the compressed jpg-format.

The M1 thinks thats a jpg... but its not, you have just to rename the png to jpg... so you can use maximum quality on this nice oled-dislpay!
